Direct an diffuse irradiance

Postby Ivana » Thu Mar 16, 2017 10:49 am

Hello everyone,

I am using WRF NMM and I need direct and diffuse irradiance in my output.
I checked my Registery and variables "SWDDIR", "SWDDNI" and "SWDDIF" have "h" in 8th column.
But when I run the model there is no variables with that name in my output.
I have DLWRF, DSWRF, ULWRF, USWRF in my output.
Is DSWRF (Downward short wave flux [W/m^2]) same as "SWDDNI" (Shortwave surface downward direct normal irradiance" "W/m^2" ")
If it is, what is diffuse irradiance?
I am using
ra_sw_physics=99
ra_lw_physics=99

Any help or advice will be helpful.
Thanks.
Ivana
